too slow ntlm
#1
HI, i have win10 + rx 5700 xt , hashcat 6.2.4 but speed is extremely low .

When im using bench it shows me 

Code:
-----------------------
* Hash-Mode 1000 (NTLM)
-----------------------

Speed.#1.........: 40515.0 MH/s (65.72ms) @ Accel:2048 Loops:1024 Thr:64


looks ok, but on real ONE hash it shows me 


Code:

coolers on fire while benchmark is running, but silence when bruteforce attack.

What is that, can anyone help me?

You are using Pure Kernel. Try -O instead:

hashcat.exe -O -m 1000 -a 3 hashes.txt maskfile.hcmask

Hi, Pure kernel even faster, you can check this in my first message. Just updated drivers to latest -21.11.1

Result for 8k hashes:

It's exactly what to expect if someone uses -S, because you will be hit full effect from PCIe bottleneck. Just remove the -S which makes no sense in context -a 3 anyway.

Refreshed page to tell you guys whats wrong and...your message is here. You are totally right. Im trying to add params one by one and all is ok now.
without -S, as u told.

Im happy now =) much more better to see
